PROBLEM TO BE SOLVED: To provide a method for manufacturing an electric contacter, capable of highly productively manufacturing an electric contacter having high stability in joining strength between a base metal and a contact point while suppressing the deformation of the base metal. SOLUTION: A rotating tool 22 which rotates at a predetermined speed and moves forward and backward to a jig and in which an end surface of a pushing side has a size not covering the entire surface of a contact point 3 is pushed into a position corresponding to the contact point 3 of a surface opposite to the contact point 3 of the base metal 1 while rotating the rotating tool 22, so that a joining surface between the contact point 3 and the base metal 1 is heated by a friction heat of the rotating tool 22 and the base metal 1 to joint solid phase diffusion bonding or liquid solid diffusion bonding, and then the rotating tool 22 retracts from the base metal 1, thereby manufacturing an electric contacter. As for the rotating tool 22, a pushing operation is repeatedly performed at a plurality of times while shifting the pushing position, alternatively, the position of the rotating tool 22 with respect to the base metal 1 is deviated while maintaining the pushing state when the rotating tool 22 is pushed into.
